Description

Aureofungin B is a polyene macrolide antibiotic derived from *Streptomyces aureofaciens*. This compound is valued for its potent antifungal activity, particularly against a broad spectrum of plant pathogenic fungi. It is primarily utilized in agricultural research and development for the formulation of biocontrol agents and fungicides. Industries involved in crop protection and agricultural biotechnology seek this product for its efficacy in managing fungal diseases.

Application

• Agricultural Fungicide Research: A key active ingredient in the development of novel, environmentally friendly fungicidal formulations for crop protection.
• Plant Pathology Studies: Used in laboratory research to study antifungal mechanisms of action and resistance in plant pathogens.
• Seed Treatment Solutions: Investigated for use in seed coating applications to protect against soil-borne fungal diseases during germination.
• Post-Harvest Disease Control: Explored for application in extending the shelf-life of fruits and vegetables by controlling spoilage fungi.
• Biocontrol Agent Development: Serves as a reference standard or a component in developing microbial-based biocontrol products.
• Pharmaceutical Precursor Research: Studied in medicinal chemistry for its structural properties in the search for new human antifungal agents.

Quality Control

Our Aureofungin B is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing specific results for purity, potency, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
